To flat shade a building’s 3D model, disable smooth shading in your 3D software and assign uniform colors/textures to each polygon face (no gradient blending).
- **What it does**: Flat shading keeps each face distinct (unlike smooth shading, which blends edges), ideal for highlighting architectural structure or a minimalist, stylized look. - **Software steps**: - Blender: Select model > Object Data Properties > Normals > Uncheck “Smooth Shading.” - SketchUp: Choose “Flat” from the Face Style menu. - **Pro tip**: If your building has separate elements (e.g., walls, roofs), color each face group first—this emphasizes structure without texture clutter.
This method ensures clean, structured flat shading for your building model.
